Read each question carefully and provide the best answer. Show all your work for calculation problems.
1. Two angles are complementary if their sum is:
90 degrees
180 degrees
360 degrees
45 degrees
2. Angles that are opposite each other when two lines intersect are called angles.
3. If two angles share a common vertex and a common side but no common interior points, they are angles.
4. Angle A measures 65 degrees. What is the measure of its complementary angle?
5. An angle measures 110 degrees. What is the measure of its supplementary angle?
Use the diagram below to answer questions 6 and 7.
6. Which angle is vertically opposite to Angle 1?
7. Name two angles that are adjacent to Angle 1.
